Embodiment
Referring to figs. 1 through Fig. 3, the utility model single cylinder is described further without outermost layer of skin belt press embodiment.
A kind of single cylinder is without outermost layer of skin belt press, the crank throw comprising crankcase 6 and be arranged in crankcase 6, described crankcase 6 side sidewall is provided with crankshaft base 3, one end of described crank throw is provided with transmission shaft 2, what described transmission shaft 2 rotated passes crankshaft base 3, described transmission shaft 2 is provided with drive unit back to one end of crank throw, the sidewall of described crank throw is provided with piston apparatus, described piston apparatus comprises oscillating bar assembly 7, cylinder 8, valve plate 9 and cylinder cap 10, one end of described oscillating bar assembly 7 is rotationally connected by bearing 11 and crank throw, the other end of described oscillating bar assembly 7 is arranged in cylinder 8, described valve plate 9 is fixed on cylinder 8 one end back to crank throw by cylinder cap 10, described crank throw comprises all identical point crank throw 4 of two size and shapes, a described point crank throw 4 is provided with attachment hole 41, two points of described crank throws 4 are formed through two attachment holes 41 successively by screw and removably connect.
When installation crank throw, because crank throw is fixedly connected with by screw by two points of crank throws 4, therefore when installation, first two points of crank throws 4 are connected on transmission shaft 2, owing to not being screwed into screw in attachment hole 41, therefore crank throw and transmission shaft 2 are not fixed, crank throw can be slided along transmission shaft 2 axial direction, thus ensure that the center of oscillating bar assembly 7 can the center of auto-alignment cylinder 8, can personal factor be effectively avoided to cause installation deviation, when behind oscillating bar assembly 7 auto-alignment cylinder 8 center, by screw, two points of crank throws 4 are being fixed again, such crank throw is also just fixed on transmission shaft 2 accordingly.
Oscillating bar assembly 7 comprises fork 71, leather cup 72 and gland 73, described leather cup 72 is fixed on one end of the relative cylinder 8 of fork 71 by gland 73, what described fork 71 was rotated by bearing 11 is fixed on crank throw, the utility model preferred version is being made up of filling polytetrafluoro material of leather cup 72, leather cup 72 is so made to have good selflubricating shape and pliability, time crank throw drives fork 71 to move, in the process that fork 71 slides in cylinder 8, leather cup 72 always with the sidewall contact of cylinder 8, when pressurized air, because gas pressure opens, be close to cylinder 8, effective minimizing is revealed, raise the efficiency, and the frictional force that can effectively reduce between fork 71 and cylinder 8 sidewall, extend the working life of fork 71,
Drive unit is belt pulley 1, because the rotating speed of belt pulley 1 is lower, can effectively reduce the rotating speed of crank throw, improves the working life of fork 71.
Crank throw is provided with fan 5 back to one end of transmission shaft 2, described fan 5 is connected with crank throw with live axle 13 by rotatingshaft 14, the axis of described rotatingshaft 14 and the axes coincide of transmission shaft 2, described live axle 13 is positioned at the side of transmission shaft 2 axis, in the process that crank throw rotates, fan 5 is driven to rotate by live axle 13, fan 5 rotates the air-flow formed and is directed to cylinder 8, force cooling cylinder 8 and oscillating bar assembly 7, effectively reduce the temperature of cylinder 8 and oscillating bar assembly 7, improve compression efficiency.
2 rotary bearings 12 are provided with in crankshaft base 3, described rotary bearing 12 lays respectively at crankshaft base 3 near one end of crankcase 6 and the one end away from crankcase 6, described transmission shaft 2 is rotationally connected by rotary bearing 12 and crankcase 6, by rotary bearing 12, effectively can reduce the frictional force in the process of transmission shaft 2 rotation and between crankshaft base, and by arranging 2 rotary bearings 12, the stability of transmission shaft 2 in rotation process effectively can be increased.
Working procedure: when compression set work, drive unit drives transmission shaft 2 to rotate, transmission shaft 2 drives crank throw rotating shaft again, that rotates due to fork 71 is fixed on the sidewall of crank throw, therefore crank throw drives fork 71 to seesaw in cylinder 8 in the process of rotating, thus reaches the effect of air in compression cylinder 8.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
